Saving on energy costs and outfitting your home or office environment with new lamps and light fixtures should be at the top of your home improvement project list.  Not only do new light sources deliver a superb quality of light, they are the key components in decorative and energy-efficient lighting design.

It is an exciting time in the lighting industry.  New products are being developed every day, and LED (light emitting diode) and SSL (solid-state lighting)*  lamps and light fixtures are at the core of future illumination.

What’s more, the integration of LEDs into building and electronic communication systems is bringing everything together and enabling total control with the ease of a smart phone!

Here are some guidelines to help you answer those questions and invest wisely toward one of the greatest home improvement projects of the decade:

WHAT YOUR LIGHTING DESIGN CAN AND SHOULD DO FOR YOU…

In addition to providing optimum levels of brightness, good lighting design must also…

•Eliminate glare

•Increase comfort

•Provide continuity

•Deliver good color rendering

•Allow for adjustability

•Instantaneously make you ”feel good” with an inviting luminous appeal

Because LED lamps require so little energy to provide a great deal of illumination, the energy consumed by the bulb will not be your main concern; your main concern will be getting the desired level of brightness and light appearance.

*NOTE:  LEDs, also referred to as SSL, provide the most energy-efficient and durable illumination because they are composed of “solid state” semiconductor light emitting diodes.

1.    Familiarize yourself with labels on new bulb cartons.

Brightness (in lumens)

Estimated Yearly Cost (depends on rates and use, $)

Lamp Life (based on 3 hrs/day use, rated in years)

Light Appearance (CCT)  (warm-cool, rated in degrees Kelvin (K))

Energy Used (in watts)

Color Rendering (CRI) (measured on a scale of 0-100)

BRIGHTNESS

Brightness levels are measured in lumens to give the amount of total light created by the light source.  Beyond the lumen count, “useable” light and brightness levels are also affected by fixture housings, lenses, filters and shades.  There are clear standards set to measure the lumen output of each LED chip.  ↓

LIGHT APPEARANCE  

Light appearance or correlated color temperature (CCT) helps determine the quality of illumination.  Designated on the Kelvin (K) scale, CCT for decorative interior spaces should be in the warm white (2700-3000K) range.  Sometimes lighting in the neutral white (3500-4000K) is preferred for certain areas, such as bathrooms and kitchens.

LAMP LIFE AND THE LED

Lamp life refers to how long a light source will last once it is installed and used on a daily basis in a typical application. Lamp life ratings, based on estimates from testing,  convey the time that half the bulbs in a sampling have burnt out or dimmed below fifty percent.

COLOR RENDERING AND THE LED

The color rendering index (CRI) measures the ability of a light source to bring out the true colors in décor, objects and surfaces.  Based on a scale of zero (no color rendering) to 100 (perfect color rendering),  a minimum of 80 CRI is acceptable for interior lighting applications.  A CRI of 90+ is even better.

However, because the standard CRI measurement does not always yield true results for some LED light sources, a new standard measure of color quality is in the works:  The Color Quality Scale (CQS) may soon replace CRI for a truer account of color rendering provided by the LED light source.-www.ledlightingexplained.com, Philips Solid-State Lighting, 2010

2.    Match light fixture to light source to ensure peak performance.

LEDs small size, low-temperature emissions, and focused uni-directional beam patterns make them perfect light sources for undercabinet lighting, track lighting and pendant fixtures.

LED general and flood lighting replacement bulbs are composed of clusters of diodes to provide broader beams of light.  General service LED bulbs that are multi-directional with 360-degree angle capacity are doing an excellent job of replicating the desired illumination of old incandescent bulbs. These LED  lamps include A19, PAR, BR and candelabra light sources that are providing more light with the added benefit of tremendous energy-saving, maintenance-free illumination.

Due to their long life and durability, LEDs are excellent in hard to reach places like foyer, attic and cathedral ceiling fixtures.

*Check for compatibility with all new light sources to make sure lamps, light fixtures, dimmers and automated controls are a suitable match.

3.    Compare “apples to apples”; diodes to diodes to ensure top quality.

 Many factors contribute to the quality of the LED light bulb.   Advancements in diode technology and mass production of LED light sources are bringing costs down to make these bulbs more affordable.  However, be wary of “cheaper” LED light sources.

•COB (chip on board), the diode itself is composed of a chip that largely determines  the quality of the bulb.

Prior to being marketed in appliances, fixtures or light bulbs, LEDs are sorted into bins according to their light output (lumen output) and color temperature.  Due to the process of “binning,” LED chips vary in their quality—especially in relation to their lumen output and color, so it is important to purchase LED light bulbs and LED light fixtures from a reputable dealer.

LEDs chosen from bins with higher lumen output are of better quality.  Color temperature is determined by matching up each LED according to a chromatic line grid for a specific color temperature.   LEDs chosen from larger bins contain more color variation , so they deliver an inferior quality of light.

•LPW (lumen per watt), this measurement helps to determine energy-efficiency and efficacy

•IC (integrated circuit) drivers, the quality of the LED lamp is also dependent on the type of driver installed.  LED bulbs contain “drivers” that can fail just like the ballast of a CFL (compact fluorescent). Better driver components make for a higher quality LED light source.

ENERGY STAR-ratings ensure that the LED has met stringent testing procedures.  ENERGY STAR-rated lamps clearly identify characteristics on LED light sources to guarantee that they consistently and reliably meet the desired brightness (lumens), energy-efficiency (lumens per watt), color temperature (CCT), color rendering (CRI), and dimmability requirements.

New ENERGY STAR Regulations include:

•Consistency Control:  More standardized testing methods to improve consistency.

•Dimmability Ratings:  A lamp is either dimmable or not dimmable.  If a lamp claims to be dimmable, testing is required and it must dim down to at least 20 percent.  If it is not dimmable, it must say so on the package.

•Greater Energy Conservation:  Efficiency requirements have increased for specific lamp wattages and types.

NOTE:  The Environmental Protection Agency (EPA), along with ENERGY STAR offers rebate programs as an added incentive to help you spring into action and upgrade with LED.  Check out rebate programs in your area or contact an American Lighting Association (ALA)-affiliated showroom for more details.

How many light bulbs have you changed in your lifetime? It’s a simple action, and often one that we don’t put much thought into, but what if the simple act of changing a light bulb could make a profound impact on the environment, and the well-being of future generations?  As experienced www.EnergyStar.gov:

“If every American home replaced just one light bulb with a light bulb that’s earned the ENERGY STAR, we would save enough energy to light 3 million homes for a year, save about $600 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to those from about 800,000 cars.”

Think about the changes that you can make by simply replacing the outdated incandescent bulbs in your home as they burn out with one of the Alternative Lighting Solutions below. Here are some details on a couple of the most popular Alternative Lighting Solutions available.

Compact Fluorescent Lamp: Modern CFL bulbs for use in homes consist of a curved fluorescent tube and electronic ballast in a single unit, designed as a direct replacement for standard blubs. They use 3-4 times less power than comparable incandescent bulbs. These are great options to replace your standard light bulbs, but they do have a few small drawbacks. According to an article by PopularMechanics.com, while CFL’s do have a much longer lifespan than standard bulbs, they often lose some of their brightness long before their expected lifespan is up, and this is increased in fixtures that don’t allow for efficient cooling of the ballast located in the base of the bulb. Another documented fact about CFL bulbs is that they do contain mercury, which means that they must be disposed of properly by taking them your local approved recycling center. You wouldn’t throw a battery out with the daily trash would you? So you shouldn’t throw these out either.

Light Emitting Diodes: LED’s are a form of “solid state” lighting that have become available recently to homeowners as an incandescent and CFL replacement. Using small light emitting diodes mounted directly to circuit boards, these are highly efficient, and have fewer parts prone to failure, allowing for an expected realistic lifespan of 20,000 to 30,000 hours, when operated at recommended temperatures. While initial costs for these bulbs are higher than incandescent and CFL options, long term energy savings are where this alternative lighting option truly shines, with the average LED bulb using approximately 12-17% of the energy that it takes to run an incandescent bulb of similar output, the end result is a bulb that costs drastically less to power over time.

As a point of comparison, here is a simple chart of the energy usage of LED and CFL bulbs compared to incandescent bulbs, and the output associated with them:

Lighting technology has changed a lot in the past decade, and it is pretty amazing to see what could be on the horizon for future lighting innovations. Take this for example. While most homes will never need this amount of output, it’s pretty impressive to see that something the size of a Christmas tree light, like this plasma bulb, can put out more light, more efficiently, than the giant bulbs that we use in street lamps!

The great thing about these changes is that they aren’t something that requires a huge change in your lifestyle, so they are some of the easiest ways possible to help the environment, and lower electric bills while you are at it!

About ElectricMan Inc.

Some home improvement projects, such as light plumbing and remodeling, lend themselves to DIY pretty easily. Larger jobs usually require highly specialized training and should only be done by a professional. This is especially true of electrical work, which is both difficult and potentially very dangerous.

What this means, of course, is you have to find a contractor you can trust! To choose a reliable contractor, it’s essential to find someone who is:

We’ll go into more detail on these:

The two most important aspects of any electrical job are safety and electrical system reliability.

Just as important as their technical skill is the electrician’s reputation. Search the internet for reviews, or ask friends and neighbors if the electrician you’re hiring does a good job and is fairly priced. It’s easy to be swindled by companies who offer rock bottom prices but deliver rock bottom service – you need to find a company that will do the job right for a reasonable budget.

Every electrical job is different, and if your electrician doesn’t know how to accommodate your particular needs, you could be in trouble. Make sure you find a contractor who has the experience and the know-how to do your specific job correctly the first time.

Finally, ask about the contractor’s warranty and insurance – and make sure you get it in writing. Does the electrician guarantee the work will meet code requirements? Will the company correct work that does not meet applicable standards? Insist on getting a written estimate as well as a copy of the contractor’s insurance certificate. Make sure your proposal or contract specifies that the work to be performed will comply with the NEC and NEIS.

Hollywood has always tried to match movies up to the seasons to draw droves of viewers to the theaters: October is packed with fright-offerings, while the winter holidays skew toward warm and pleasing family films (as well as Oscar hopefuls). Valentine’s Day falls in an odd spot when it comes to the movie release calendar, however, since February tends to be a slower time for the film industry. The studios are as likely to slot strange movies that don’t fit anywhere else in their annual schedules into the Valentine’s Day weekend as they are films with powerful romantic appeal.

So, while the second weekend of February has featured hugely successful romantic comedies like Hitch, The Wedding Singer, and (of course) Valentine’s Day, some truly weird choices have debuted in this weekend as well. And a few have even gone on to tremendous success despite the bizarre match with the holiday. Here are a couple of the odder Valentine’s Day movie releases:

Whether you celebrate Valentine’s Day with a trip to the movie theater, or you have your own special plans, everyone here at FB Electrical Services hopes you and your loved ones have a wonderful weekend.

The lighting of your kitchen plays an absolutely critical role in how your design will marry together, as well as make a very noticeable impact on the functionality of your space.

Many homeowners put off or ignore lighting in the kitchen, and neglect to plan accordingly. This can only end in tears! What is the benefit of those gorgeous mahogany cabinets, and that handsome granite counter top if no one can see them properly?

Don’t find yourself regretting your kitchen design decisions. Take lighting into account right off the bat! But how do you plan for your kitchen lighting? There are a few types of light to consider, and it all comes down to how you want your kitchen presented, and more importantly, how you want it used. Consider these lighting types for your perfect kitchen design.

For the sake of giving off the best lighting possible for visual appeal, consider these:

Task lighting is used to provide ample illumination for performing specific tasks (thus: task lighting), and should be installed with a specific purpose in mind. This could be for your stove top, a cutting and preparing area, or a space devoted to work or play. Task lighting is best used when it provides ample, glare-free lighting. These fixtures work particularly well:
